1. Prepainted Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized or galvalume steel sheets.
2. The base metals for Prepainted Steel Coil consist of cold rolled, HDGI Steel, electro-galvanized and hot-DIP alu-zinc coated steel. The finish coats of Prepainted Steel Coil can be classified into groups as follows: Polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.
3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.
4. The color of the Prepainted Steel Coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.
5. The Prepainted Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.

Yes, all of our PPGI and GI was qualified before shipping. We test every batch every day

Q: I have heard using the BRASS casing is the best thing for an AR-15? Should i just use Brass or Steel?: No. People who say that don't use steel cased ammo. It it said its harder on the extractor. I don't see how. Its dirtier because it doesn't expand like brass does but the steel casing is still softer than the steel of the gun. That is a mild steel which isn't as hard as what most people are thinking of.

Q: How are steel coils used in the manufacturing of shock absorbers?: Steel coils are used in the manufacturing of shock absorbers primarily as a spring component. These coils provide the required strength and flexibility to absorb and dampen the impact and vibrations experienced by the vehicle. When compressed or expanded, the steel coils store and release energy, ensuring a smoother and more controlled ride for the driver and passengers.

Q: I haven't seen Man of Steel yet, but which one do you think was better? (please no spoilers): Well, I haven't seen it Man of Steel but I really see it hard to believe that's better than Superman. To me, Superman with Christopher Reeve is the best movie about Superman ever made. When I first saw it I was amazed. Watching Superman flying for the first time, catching Loise and graving that helicopter before it falls... it was awesome! I loved it! The other movies that followed were bad but this one was amazing. I've seen what other actors have made with the character, but I believe Christopher was the best. He was the perfect man, the perfect gentleman and the best superhero ever. I know that this Superman is for the new generations so it will be more 'real' and more 'suffered' or will have more personal issues dealing with his origins and blah blah blah... and I wish him good luck, but honestly? I stick to the original Superman because whenever I see Christopher Reeve flying around the planet as Superman (hanging from wires-no CGI people!) and I hear that characteristic music I just melt and I'm a child once more. So good luck to the new generation, I really hope they like this new guy and new story, but I'm more than fine with the original version, thank you. Hope it helps! ;)

Q: How are steel coils used in the oil and gas industry?: Steel coils are commonly used in the oil and gas industry for various purposes such as manufacturing pipelines, storage tanks, and offshore platforms. These coils are formed into cylindrical shapes and serve as the main structural component for these applications, providing strength, durability, and resistance to extreme conditions. Additionally, steel coils are used in the production of equipment like heat exchangers, compressors, and drilling machinery, which are essential for the extraction, processing, and transportation of oil and gas.

Q: which type of carbon steel does not have manganese: None. Mn is a trace impurity in all steels, if you look carefully enough. If you want to find a steel where Mn is not intentionally added, start looking at the alloy composition specifications, there are hundreds of steels. Why are you worried about Mn? Mn is typically added to steels for a very good reason.

Q: How are steel coils used in the manufacturing of garage doors?: Steel coils are used in the manufacturing of garage doors as they provide the necessary strength and durability required for the door panels. These coils are formed into various shapes and sizes to create the panels, which are then coated and insulated to enhance their performance and appearance. The use of steel coils ensures that the garage doors are sturdy, long-lasting, and able to withstand the daily wear and tear associated with regular use.

Q: How are steel coils inspected for surface defects using non-destructive testing methods?: Steel coils are inspected for surface defects using non-destructive testing methods such as visual inspection, magnetic particle inspection, and eddy current testing. Visual inspection involves closely examining the coil's surface for any visible defects or abnormalities. Magnetic particle inspection is used to detect surface cracks and defects by applying a magnetic field and then applying iron particles that reveal any magnetic leakage caused by defects. Eddy current testing is employed to detect surface cracks and defects by inducing an alternating current in a coil that creates a magnetic field, and any changes in the field caused by defects are detected. These non-destructive testing methods help ensure the quality and integrity of steel coils without causing any damage.

Q: How are steel coils inspected for quality control purposes?: Steel coils are inspected for quality control purposes through a combination of visual inspection, dimensional measurements, and various non-destructive testing techniques. This includes checking for surface defects, such as scratches or dents, as well as verifying the dimensions, weight, and shape of the coils. Additionally, technologies like ultrasonic testing, magnetic particle inspection, and X-ray examination are employed to detect internal defects, such as cracks or inclusions, ensuring that the steel coils meet the required quality standards.

Q: What are the common defects found in uncoiled steel coils?: Some common defects found in uncoiled steel coils include edge waves, center buckles, coil breaks, surface defects such as scratches or dents, and variations in thickness or width.
